Application filed. October 13, 1920. 7 Serial No. 416,745.

1 0 all 10 item it may concern Be it known that l, STONEWALL J. CAP.-OLAND, a citizen of the United States, residing at Woodlawn, in thecounty of Montgomery and State ofTennessee, have invented a new anduseful Hoop-Coiling Machine, of which the following is a specification.

This invention relates to hoop coiling machines, it being the bject ofthe invention to improve the structure and utility of the device onwhich a patent was granted me, under date of Uctober 18, 1903, and whichbears Patent Number 741,109.

An object of the invention is to provide means forming a part of themachine for securing the hoop to the machine in a manner to prevent thesame from working out of the coiling device.

A further object of the invention is the provision of novel means forguiding the hoop to the ceiling device to insure the same enteringdirectly under the coiling strip.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of constructionhereinafterdescribed and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed, may be madewithin the scope of what is claimed, without departing from the spiritof the invention.

Referring to the drawing Figure 1 illustrates a side elevational view ofa hoop coiling machine constructed in accordance with the presentinvention.

Fig. 2 is a plan view of the same.

Referring to the drawing in detail, the reference character 5 designatesthe base of the machine, to which are secured the supporting legs 6,which in turn support the table 7.

Supported by the base 5 and table 7, is an operating shaft 8 which hasits upper extremity extending an appreciable distance above the table 7,where the same supports the pulley 9, which accommodates belt from anysuit-able power device not shown.

Secured to the shaft 8 and operating at a point adjacent to the table 7,is a coiling drum 10 around which the hoops pass during the coilingoperation, a hoop being indicated in the drawing by the referencecharacter 11, for the sake of illustration. Associated with the drum 10,is a strip 12 formed preferably of flexible metal, the strip having oneof its ends anchored to the table 7 at 13, the intermediate portionthereof being extended around the drum 10, while the opposite end of thestrip has connection with the coiled spring 14 as through the medium ofthe link 15.

This coiled spring 14 has one end thereof secured to the extension 16formed at one end of one of the legs 6, there being provided an eye bolt17 passing through the extension for connecting the spring to the frame.A nut 18 operates on one end of the threaded eye bolt to provide for anadjustment of thecoiled spring 14 to permit the tension on the strip 12to be changed or regulated to meet various requirements.

Glamping fingers 19 cooperate with the coiling drum and overlie aportion thereof to restrict movement of the hoop vertically when hoopsare being applied to the coiling drum, thereby eliminating anypossibility of the hoops becoming displaced from the drum 10.

To further insure against vertical movements of the hoops, a pivotedlever 20 is provided, which pivoted lever has connection with the table7 as at 21, the opposite end of the lever being disposed at a pointunder the hook member 22, which also has pivotal connection with thetable to move upwardly into engagementwith the lever to lock the leverin its securing position.

This lever 20 is of a length to overlie p01" tions of the strip 12 andthe hoop under operation, and is designed to contact with the forwardportion of the hoop when the same is being passed into or between thestrip 12 and drum 10.

Secured to the upper end of the shaft 8, is a sweep 23, which preferablyextends at an angle, and carries the whiiiietree 241: on one endthereof, by means of which the shaft 8 is rotated by any suitable draftanimal.

In the operation of the device, a hoop is secured to the drum 10 as bymeans of the pin 25, whereupon the shaft 8 is rotated to draw the hookbetween the drum 10 and Strip 12.

When the hoop passes into the machine, a predetermined distance, theforward end of a second hoop is introduced between the rear end of thefirst hoop and the periphery of the drum, and the continued motion ofthe drum causes the second hoop to be wound on the drum outside of thefirst mentionec hoop.

Having thus described the invention, what is claimed as new is In a hoopcoiling machine, a frame, an operating shaft mounted on the frame, adrum secured to the operating shaft to move therewith, a strip offlexible metal having one end anchored to the frame at a point adjacentto the drum, resilient means for connecting the opposite end of theflexible memher to the frame, clamping fingers carried by the frame andoverlying the upper edge of the drum, a pivoted lever adapted to moveacross one corner of the drum and contact with the flexiblernember at apoint adjacent to the periphery thereof, and means for operating theshaft.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature inthe presence of two witnesses.
